Anterior Monteggia injuries are frequently complicated by persistent radial head instability and suboptimal outcomes. Using a cadaveric elbow motion simulator, we quantified the contributions of ligaments of the proximal radius on maintaining radial head stability, evaluated the effectiveness of ulnar overcorrection to create an apex dorsal angulation in stabilizing the radiocapitellar joint, and finally compared the stabilizing effect of annular ligament repair to three different reconstruction techniques. Our results showed increased anterior radial head translation with progressive soft tissue sectioning with the annular ligament as the primary stabilizer. Ulnar overcorrection and forearm pronation were shown to decrease anterior translation of …

Anterior Monteggia fracture-dislocations are frequently complicated by persistent radial head instability leading to suboptimal outcomes. In this biomechanical investigation using a cadaveric elbow motion simulator, we examined the effects of ulnar extension angulation, soft tissue disruption, biceps loading and elbow motion on radial head translation. Our results showed significant anterior radial head translation with progressive ulnar extension angulation, with greater soft tissue injuries and increased biceps loading (P=.000). There was no significant difference in radial head translation between simulated active and passive elbow flexion (P=.251). These findings support the importance of an anatomic reduction of the ulnar fracture. However, in …
